Is it possible to derive Le?
type: item
description: Hi Wayne. I wonder if we can derive Le (@1kHz) for a driver(?), having all the other T/S parameters for the same driver. I know there is a relation with Mms (and that there is another relation with Cms) but I am not sure if we can get it, or close. I have the measuring tools (from Kirshner/Germany) but I need a new laptop to put them to work, in the long run. I also congratulate you for the help you give, to all of us, on the diyAudio Forums. Thanks

description: I think it might be more useful to measure it. It'll give you an excuse to get that measurement system running! Be sure to measure at various drive levels.

description: Well, yes, I think I would not allow any LF signals to be generated. Start the sweep relatively high, just under the frequencies of interest.
